LAMP-SHADE surron'r.

To all whom it may concern Be it known that we, ANDRE-W the UnitedStates of America, residing at New Haven, in the county of New Haven andState of Connecticuhhave invented. a certain new and useful Improvementin Lamp-Shade Supports. of which the following is a full, clear, andexact description,

This invention relates to means for, sup porting lamp shades from lamps,such as the globes of electric lamps.

An important feature of the invention, is comprised in a device of thecharacter referred to which is constructed of sheet ma terial andpreferably of sheet metal, and embraces a pair of diametrically.opposite lamp-engaging members which are connected with a shade, andhave suflicient resiliency to maintain engagement with the bulb of thelamp and at the same time to permit angular adjustment of the shade.

Another important feature of the invention consists in a lamp shadesupport of the character referred to in which the lamp engaging membersterminate in circular clamping portions which are of sheet metal whichis bent or distorted transversely of its plane circumferentially toprovide a curved or rounded surface for contact with the lamp bulb,thereby strenghtening the clamping members and providing afinishedsurface on said members for engagement with the bulb.

Other features of the invention, such as important details ofconstruction and combinations of parts, will be best understood from thefollowing description, and the novel elements will bepointed out in theappended claims.

In the drawings:

Fig. 1 represents a lamp shade in section, and the shade support inelevation, said shade supportbeing in normal position on a bulb. I

Fig. 2 isa side elevation of the support taken at right angles to Fig.1, and

Fig. 8 is an inverted plan View of Fig. 2.

The shade supporting device comprises two members made of sheetmaterial, such as sheet metal. One of said members comprises a terminalflat portion 1, with acentral perforation, a downwardly inclined arm 2and a circular bulb-engaging part 4, and the other member comprises aterminal flat J7. GAR" MICHAEL and JOHN R. Pn'rm-zson, citizens ofportion 6' having a central perforation, a

downwardly inclined arm 3, and a terminal cir cular bulb-enga ingjportion 7. The Hattened portions 1, d

are arranged witl' their apertures in alignment and a clamping screwhaving shank 8, and head-1O is passed" through the alignedperforationsal'id other perforations 111 a washer 11 and thetop centralportion of the shade 1 2, said'shanl': be- 9 I ing received in athreaded socket ofanor -a namental knob 14,-which cooperates with thescrew in firmly securing the several parts together. 1 i

Preferably, the circular. bulb clamping parts 4, 7, are benttransverselyof the planes.

in which they lie to form convexly curved lamp-engaging ribs 15 whichnot only act to stiffen the members, but also provides a finished edgefor engagement with the surface of the bulb B- When the parts of theshade support are assembled and clamped to the shade, as shown inFig. 1,it will be seen that the arms 2, 3 may extend outwardly and downwardlyat aninclination and that the circular terminal portions like wiseextend divergently, and engage the upper globular surface of the bulb.The maerial of which the members of the clamp is composed is preferablyresilient sheet metal is tilted, within certain limits, but these limitsare sufficient for all practical pur poses.

While we have shown the support as comchanges as fall within the scopeof the following claims.

What we claim and desire to secure by United States Letters Patent is:

1. A shade support comprising, in combination, a plurality of flat sheetmetal arms arranged to extend divergently from a central point ofconnection with a lamp shade, said arms terminating in circularlamp-engaging portions. said circular portions being a bent transverselyof their planes to form oonveXly curved lamp-engaging surfaces.

2. A device of the class described, comprising, in combination, two armsof resilient sheet material arranged to extend divergently downward andterminating in circular lamp-engaging portions which are benttransversely of 1 their planes to. present curved lamp globe engagingsurfaces, and means for rigidly securing said members to the insidecentral portion of a lamp shade.

set our hands this th {3. A device of the class described, comprising,in combination, two arms each having a terminal flattened portionprovided with a perforation, and a downwardly ex tending outwardlyinclined portion termiforations of said flattened portions andthrough asimilar perforation in a lamp shade, and a clamplng knob to engage saidmeans and cooperate therewith to secure said members to the shade.

In testimony whereof day of February A. D. 1923. 1 p i ANDREW J.CARMIOHAEL. JOHN R. PETERSON.
